# Simplifying Node Network

Nodegraph clarity is an important topic for every node-based pipelines. By nature, node networks become complex and hard to read. To address the issue, simplifying tools are essential. 

Reality Hub offers [Node Context Menu](/docs/reality-5.3/reality-5.3/user-guide/nodegraph-actions/nodegraph/node-context-menu.md) features for better readability such as [Portal Pin](/docs/reality-5.3/reality-5.3/user-guide/nodegraph-actions/nodegraph/portal-pin.md), Hide Unused Pins, Rename Node, [Node Comment](/docs/reality-5.3/reality-5.3/user-guide/nodegraph-actions/nodegraph/node-comment.md), etc.

### Stages

#### First Stage

In the first stage, we create **Portal Pins** for commonly used connections, such as the <mark style="color:green;">**`SingleLink 1`**</mark> output of the <mark style="color:yellow;">**`AJAIn`**</mark> node, the <mark style="color:green;">**`Track`**</mark> output pin of the <mark style="color:yellow;">**`Xync`**</mark> node, and the <mark style="color:green;">**`Lens Distortion`**</mark> output pin of the <mark style="color:yellow;">**`Break Track`**</mark> nodes.

#### Second Stage

In the second stage, we group various nodes using the **Create Comment From Selection** option and assign them meaningful names like Camera Tracking, Talent Tracking, Cyclorama, RealityKeyer, and Compositing and Rendering.

#### Third Stage

In the third stage, we rename various nodes that share the same name, such as <mark style="color:yellow;">**`Break Track`**</mark>, <mark style="color:yellow;">**`Distort`**</mark>, and <mark style="color:yellow;">**`Undistort`**</mark> nodes, using the **Rename** option. This helps prevent confusion and incorrect connections when working on relatively complex nodegraph operations.&#x20;
